Conditional sentences are used to talk about situations and their consequences. In English, different types of conditionals are used depending on whether we are talking about facts that are always true or possible events in the future.
✅ Zero Conditional: Facts and Things That Always Happen
The zero conditional is used for situations that are always true. It shows a cause and effect relationship that does not change.
Examples:
- If you heat water to 100°C, it boils. 💧
- If it rains, the ground gets wet. 🌧️
- If I am tired, I go to bed early. 🛏️
Key points:
- Used for facts, routines, or general truths.
- Both parts use the present simple tense.
✅ First Conditional: Real Possibilities in the Future
The first conditional is used for possible events in the future and their likely results. It is often used for predictions, warnings, promises, or advice.
Examples:
- If it rains tomorrow, we will stay at home. 🌧️🏠
- If I study hard, I will pass my exam. 📚
- If she doesn’t hurry, she will miss the bus. 🚌
Key points:
- Talks about possible future situations.
- The if-part uses present simple, and the result uses will + base verb.
